Colour
Conductive wearing layer available in many colours.
Applied colours selected from colour charts will be approximate.
Colour deviations may occur due to carbon fibre filaments.
For colour matching: Apply colour sample and confirm selected colour under real lighting conditions.
When product is exposed to direct sunlight, there may be some discolouration and colour variation, this has no influence on the function and performance of the floor finish.

+10 °C minimum / +30 °C maximum
Ambient Air Temperature
+10 °C minimum / +30 °C maximum
Relative Air Humidity
80 % maximum
Dew Point
Beware of condensation. The substrate and uncured applied floor materials must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product.
Substrate Temperature
+10 °C minimum / +30 °C maximum
Substrate Moisture Content
≤4 % parts by weight. The following test methods can be used: Sika®-Tramex Meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).
Waiting Time / Overcoating
Before applying Sikafloor®-221 W Conductive on Sikafloor®-156/160/161 allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 24 hours | 4 days |
| +20 °C | 12 hours | 2 days |
| +30 °C | 8 hours | 1 days |
Before applying Sikafloor®-262 AS N on Sikafloor®-221 W Conductive allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 26 hours | 7 days |
| +20 °C | 17 hours | 6 days |
| +30 °C | 12 hours | 4 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

Consumption
| Coating | Product | Consumption |
| 1. Primer | Sikafloor®-150/-151 | 1–2 × ~0,3–0,5 kg/m² |
| Levelling (if required) | Sikafloor®-150/-151 Levelling Mortar | Refer to PDS of Sikafloor®-150/-151 |
| 2. Conductive Primer & Earthing Connection | Sikafloor®-221 W Conductive Sika® Earthing Kit | 1 × 0,08–0,10 kg/m² 1 earthing point per ~200–300 m². 2 per room minimum |
| 3. Self-smoothing Wearing Layer for High Aesthetical Finish ~1,5 mm thickness | Sikafloor®-262 AS N filled with Sikafloor® Filler 1*1 | Maximum 2,5 kg/m² Binder + Sikafloor® Filler 1. Filled: 0,1–0,2 parts by weight |
| Self-smoothing Wearing Layer ~1,5 mm thickness | Sikafloor®-262 AS N filled with quartz sand F34*1 | Maximum 2,5 kg/m² Binder + quartz sand F 34. Filled: 0,1–0,3 parts by weight |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
*1 All values have been determined using quartz sand F 34 (0,1–0,3 mm) from Quarzwerke GmbH Frechen and Sikafloor® Filler 1. Other quartz sand types will have an effect on the product, such as filling grade, levelling properties and aesthetics. Depending on the air temperature, the filling grade varies, generally, the lower the temperature the less the filling grade.
